Abstract (en)
[origin: US2018267246A1] An aspect of the disclosure provides a microring resonator (MRR). Such an MRR includes a ring optical waveguide and an optical waveguide, with the optical waveguide configured such that a first portion of the optical waveguide overlaps a second portion of the ring waveguide. In some embodiments, the optical waveguide has a first refractive index and the ring optical waveguide has a second refractive index such that the first refractive index is less than the second refractive index. In some embodiments, the optical waveguide is a polymer optical waveguide and the ring optical waveguide is a silicon optical waveguide. In some embodiments, the optical waveguide is larger in height than the ring waveguide and the first portion of the optical waveguide is configured to provide space for the second portion of the ring waveguide.
